Wakefield Biochar Facility 2

Integrity

The verification report (2025-12-17) reports a reversal event: changes in biochar production and monitoring methods resulted in a negative balance of 5,360 CORCs, which is a direct integrity concern for a removal credit. The baseline is described as project-specific and the additionality approach is an investment test, but confirmation of additionality by the VVB and any baseline reassessment timing were not found in the extracted record. No material findings were reported in the verification report, but the number and nature of corrective actions suggest underlying quantification/control weaknesses that can affect integrity.

Transparency

The verification report (2025-12-17) provides a defined monitoring period (2025-01-01 to 2025-09-30) and identifies the VVB as EnergyLink Services. However, the extracted record does not include total removals claimed or verified, making it hard to independently assess issuance accuracy. Several monitoring/quantification specifics (e.g., usage monitoring method, leakage treatment) were not found in the extracted record, reducing transparency.

Claim Safety

Claim safety is weakened by the reported negative balance of 5,360 CORCs in the verification report (2025), which signals that previously expected removals may not have been durable or correctly accounted for under updated methods. The verification report also lists multiple corrective actions (LCA boundary, moisture content, emission factor, and transport), which are common drivers of over-crediting risk in biochar LCAs. CORSIA eligibility and CCP status were not found in the extracted record, so the risk of inappropriate downstream claims cannot be ruled out.

Documentation

A recent verification report dated 2025-12-17 is present, and the extraction indicates 11 documents were used, which supports documentation completeness. Still, the evidence document list is not well specified (listed as "unknown"), and extraction confidence is only medium, implying some limitations in document readability/structure. The presence of multiple corrective actions in the verification report also suggests documentation and data systems required remediation during assurance.

Overall

Overall quality is constrained primarily by the reported reversal/negative balance (5,360 CORCs) and the concentration of corrective actions around LCA boundary and key parameters, which together elevate over-crediting and durability/accounting risk. Transparency and claim safety are further limited because key quantitative fields (claimed/verified removals, leakage deduction, buffer pool) and eligibility statuses (CORSIA/CCP) were not found in the extracted record. No contradictions were identified in the extracted record, so no cross-document discrepancies needed resolution.
